Maybe not possible for you, but where I live (Germany) the obvious solution would be to get 2 cheap used bikes for both start/end legs and chain them at the station.
The dangerous place is not the straight road, but crossings where cars turn right and hit cyclists going straight. So the way these spots are handled is way more important than painted line vs fence.
Additionally you need to test it doesn't trigger a positive when someone had a cinnamon flavored mint before. Or a citrus one. Or ate a mushroom sandwich. Or has diabetes..etc etc
